Answer:

Infrared

Explanation:

Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark. Infrared light has frequencies which are absorbed by some chemical bonds. The internal energy of the bonds increases when they absorb infrared light, which causes heating.

For the reaction
azamat

Answer:

Mass = 5.56 g

Explanation:

Given data:

Mass of Cl₂ = 4.45 g

Mass of NaCl produced = ?

Solution:

Chemical equation:

2Cl₂ + 4NaOH     →   3NaCl + NaClO₂ + 2H₂O

Number of moles of Cl₂:

Number of moles = mass/molar mass

Number of moles = 4.45 g/ 71 g/mol

Number of moles = 0.063 mol

Now we will compare the moles of Cl₂ with NaCl.

                  Cl₂         :         NaCl

                    2          :          3

                 0.063      :        3/2×0.063 =0.095 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 0.095 mol × 58.5 g/mol

Mass = 5.56 g

Solid foods digest faster than liquids.
Alexeev081 [22]
The answer to this question would be: false

Solid foods have a smaller surface that can be digested by enzyme compared to the liquids food. Liquid food like milk can easily be digested as the substrate spread in the solution to the enzyme can bind freely to the substrate. In solid food, the area that can be digested would be only the outer part of the food. That is why organism have teeth so the food can be cut into smaller pieces, increasing the surface area that can be digested.
